摘要
本文针对悬沙浓度沿水深分布的特点，通过探索悬沙农度与图象灰度的关系，提出了一种利用数字图象处理技术测量明渠悬沙浓度的方法，并将测量成果与广泛应用的扩散理论计算结果进行了比较，两者基本吻合，这说明该项技术在用于悬沙浓度测量时，不失为一种有效方法。随着计算机图象处理和摄像技术的不断发展，本文所述方法在测量精度和适用范围方面还将不断提高，并可望用于实验研究和工程实践中。
After studying the ralation between the concentration of suspended sediment and the gray level of image,the Digital Image Processing Technique(DIPT)as a new method is introduced to measure the concentration of suspended sediment in open channel The results are close to the value which calculated by the diffusion theroy With the development of computer and camera technique,the new measuring method will be improved and used in the experiment and engineering practice
